Title: Improvements relating to ignition magnetos for internal combustion engines
IPC: F02P1/00
Filed: 1935-12-20
Abstract: 467,592. Snap-action switches. LUCAS, Ltd., J., and ALLEN, A. MASSEY-. Dec. 20, 1935, Nos. 35297/35 and 11893/36. [Class 38 (v)] A switch for making and breaking the circuit of one of a pair of ignition interrupters has mechanism comprising an operating lever which may be actuated by hand or automatically, a fixed switch contact, a movable switch contact and a second lever responsive to the action of the operating lever and a spring or springs whereby the movable contact is caused to assume the same position relatively to the fixed contact for each end position of the operating lever, the arrangement being such that the contacts are closed (or opened) when the operating lever assumes either of its end positions and are opened (or closed) when the operating lever assumes an intermediate position. As shown in the Figure, the free end of operating lever m, which may be moved through an angle either manually or automatically as by the carburetter control, bears against one arm k of a bell-crank. The other arm i of the bell-crank is connected by a spring h to a contact lever f pivoted at i and when the free end of lever m comes opposite the recess o in the lever k in the middle of the range of movement of the operating lever the bell-crank is rotated in a clockwise direction by a spring p. This rotation brings the line of action of the spring h across the pivot of the contact lever so that the contacts e, d in the primary connection of one of the interrupters are separated. To ensure movement of the contact arm in case the contacts adhere, the bell-crank carries a forked arm s into which projects a springy arm r attached to the arm f so that after an operating movement of the bell-crank the arm r is positively moved by the forked member s. In a modified arrangement, Figs. 3 and 4 (not shown), the forked arm engages a lateral portion of the contact arm itself and the recessed segment is provided on the operating lever. The dead-centre spring for the contact arm is in this form replaced by a shaped spring bearing on the shaped end of the coiled lever to maintain it in or out of contacting engagement. In a further arrangement described, Figs. 5 and 6 (not shown), features of both arrangements are combined.

Title: Improvements relating to fire extinguishing apparatus
IPC: A62C13/00
Filed: 1928-11-30
Abstract: 325,849. Pyrene Co., Ltd., (Pyrene Manufacturing Co.). Nov. 30, 1928. Kinematograph apparatus.-In a projector the fusion of a link upon an outbreak of fire is arranged to release a piercer for a compressed gas capsule; the gas may act as an extinguishing agent, or may be arranged to force an extinguishing liquid from a container into spraying pipes. As shown, a gas capsule 5 and a liquid container 4 are mounted on the upper reel-compartment 1, Fig. 2. A piercer 6 is arranged below the capsule 5 and a gas-delivery pipe 7 leads from the capsule outlet to the upper end of the container 4. A liquid discharge, pipe 9, 17 is arranged around the projector with discharge nozzles 18 at suitable points. The pipe portions 9, 17 are connected by a valve chamber 10, Fig. 6, and separated by a valve 11 which is normally held closed by a pivoted plate 13 supported by a cage 15 pivoted over an opening 21 in the compartment 3 containing the film-driving mechanism. The cage 15 is held up by a celluloid link 25 and contains readily inflammable matter 23. In case of fire in the compartment 3, the link 25 is fused, the cage 15 drops about its pivot, and the valve 11 is opened. Some liquid can escape from the valve chamber by a groove and nozzle 19. The remainder passes to the pipe 17 and nozzles 18. The fusion of the link 25 also releases a link system 28, 29, 32 so that a spring 33 is free to move a lever 34. This disengages a catch 36 from a hammer 45, which is then forced upwardly along the piercer stem 43 by a spring 46 until it engages a collar 48 on the stem, causing the piercer to open the capsule 5. The capsule is held firmly in a cup 37 by a screw 40 mounted in a yoke 55 pivoted at 56 to the cup 37. Links 57 are pivoted to the yoke at 58, and at their lower ends to blocks 60. When the screw 40 is released to replace. a capsule 5, the yoke is swung forwardly about the pivots 56, causing the links 57 and blocks 60 to move downwardly. Shoulders on the blocks then engage the hammer 45 and force it down against the spring 46 until it is re-engaged by the latch 36. The closing cap 63 of the container 4 is carried by a pivoted yoke 64 to facilitate recharging, and the neck of the container is connected to the discharge pipe by a short antisyphon pipe. A pipe 50 branching from the gas-delivery pipe 7 leads to a cylinder 51 containing a plunger 54 mounted behind a pushbutton 53 controlling a switch 52 for the motor which drives the projector mechanism. By this means, the mechanism is stopped as soon as the extinguisher comes into operation.

Abstract: 866,161. Combustible gases. POWER-GAS CORPORATION Ltd. Nov. 21, 1957 [Nov. 22, 1956], No. 35684/56. Class 55 (2). Combustible gases are produced by passing a mixture of gaseous or vaporized hydrocarbons and an oxidizing gas through a reaction zone which is maintained at a temperature below 700‹ C. and which contains radioactive material emitting gamma rays or beta particles or both. Hydrocarbon gas or vapour is supplied at 11, and steam, preferably superheated, at 13, so that the mixture passes through connection 7 to a tube 1 which is suspended in a furnace 18. The radioactive material 6 is contained within a metal tube 2 so that gamma rays pass into the reactants in tube 1. The resultant gases are taken off at 17. The temperature in the reactor may be 350‹ C. to 550‹ C. and the pressure between 1 and 30 atmospheres. In a modification carbon dioxide replaces the steam. To reduce the formation of free carbon, air or oxygen may be added to the reactants through line 15. Alternatively, at intervals the reactor may be taken " off stream " and air or oxygen, with or without steam, passed into the reactor to remove the carbon by gasifying it. A number of reactors may be enclosed by the furnace 18, each reactor being taken " off stream " in turn. In a modification the reactor tube 1 is filled with radioactive material which is supported on a grid at the base of the tube 1. The reactants are then subjected to the influence of beta particles as well as gamma radiation and the product combustible gas is scrubbed and/or filtered to remove entrained radioactive particles. When using a hydrocarbon liquid, it may be mixed with superheated steam and the mixture passed through a preheater, which may be heated by the products of combustion of the furnace. Alternatively liquid hydrocarbons may be vaporized before mixing with the steam or carbon dioxide. The radioactive material may be cobalt 60, caesium 134 or 137, europium 154 or 155, nickel 63, technetium 99, promethium 147, thallium 204, ruthenium 106, or strontium 90.
